Abstract
The invention provides an environmental controller with a secure digital (SD) card for a livestock and poultry transport vehicle, which comprises a central processing unit. The central processing unit is connected with a communication interface, a clock circuit and a power supply circuit respectively and characterized in that: an input end of the central processing unit is connected with a temperature sensor, a humidity sensor and a keyboard input circuit respectively; an output end of the central processing unit is connected with a liquid crystal display circuit and the SD card; and the output end of the central processing unit is connected with a heater through an analog output circuit, and is connected with a constant speed fan through a switch quantity output circuit. The environmental controller can be used for the ventilation control of the livestock and poultry transport vehicle and controls the environmental temperature and humidity in the livestock and poultry vehicle within a set curve through measures such as ventilation, heating, refrigeration and the like according to a signal of the temperature sensor at the same time so as to meet the requirements on the long-term transportation of livestock and poultry. The central processing unit has an SD card memory function, so temperature variation conditions during the operation can be recorded in real time and queried through a PC.
Description
Technical field
The present invention relates to a kind of livestock and poultry transport vehicle environmental control, be used for the environment control of livestock and poultry transport vehicle, belong to livestock and poultry transport vehicle environmental control technical field with the SD card.
Background technology
In the market hold fowl transport vehicle major part all be open type or increasing air conditioner modifying with box car forms, these two kinds are held the fowl transport vehicle and are not all had environmental control, even there is minority to hold the fowl transport vehicle environmental control is arranged, these controllers all do not have the SD card and are very simple on function yet.
The SD card is the abbreviation of Secure Digital Card card, and literal translating into Chinese is exactly " safe digital card ", is by the common brand-new multifunctional storage card of developing of MAT, Toshiba and U.S. SANDISK company.The SD storage card is a wide-open standard (system).
Summary of the invention
The multi-functional livestock and poultry transport vehicle environmental control that the purpose of this invention is to provide a kind of SD of having card.
In order to achieve the above object, technical scheme of the present invention provides a kind of livestock and poultry transport vehicle environmental control with the SD card, comprise central processing unit, central processing unit connects communication interface respectively, clock circuit and power circuit, it is characterized in that, the input end of central processing unit connects temperature sensor respectively, humidity sensor, the keyboard input circuit, the output terminal of central processing unit connects liquid crystal display circuit and SD card, the output terminal of central processing unit connects well heater by analogue quantity output circuit, and the output terminal of central processing unit connects the constant speed blower fan by the switching value output circuit.
The output terminal of described central processing unit also connects alarm module.
Advantage of the present invention is: the Ventilation Control that can be used for livestock and poultry transport vehicle, while is according to the signal of temperature sensor, by measures such as ventilation, heating, coolings, the ambient temperature and humidity in the livestock and poultry car is controlled at the curve of a setting, to satisfy the requirement of livestock and poultry long period transportation.Central processing unit is furnished with SD card memory function, but real time record temperature variations in service, and can inquire about with curve and data form form by PC.
Description of drawings
Fig. 1 is the circuit block diagram of the livestock and poultry transport vehicle environmental control of band SD card.
Embodiment
Specify the present invention below in conjunction with embodiment.
Embodiment
As shown in Figure 1, circuit block diagram for the livestock and poultry transport vehicle environmental control of band SD card, described livestock and poultry transport vehicle environmental control comprises central processing unit, central processing unit connects communication interface respectively, clock circuit and power circuit, the input end of central processing unit connects temperature sensor respectively, humidity sensor, the keyboard input circuit, the output terminal of central processing unit connects liquid crystal display circuit, alarm module and SD card, the output terminal of central processing unit connects well heater by analogue quantity output circuit, and the output terminal of central processing unit connects the constant speed blower fan by the switching value output circuit.
Central processing unit is selected the MicroChip PIC18F452 of little core company for use.
In use, need the program that burning weaves in CPU (central processing unit) earlier, entire equipment effectively operation under the control of program then, its process is: by the keyboard input circuit environment in the livestock and poultry transport vehicle and temperature are provided with earlier, the concrete value that is provided with is shown that by liquid crystal display circuit CPU (central processing unit) is adjusted well heater and constant speed blower fan according to the value of temperature sensor and humidity sensor by analogue quantity output circuit and switching value output circuit subsequently.Simultaneously, equipment of the present invention also can directly directly be set the value of well heater and constant speed blower fan by the keyboard input circuit.
Environment temperature in the complete closed livestock and poultry transport vehicle and humidity are controlled, also be provided with minimum ventilation curve and can guarantee the livestock and poultry supply of the oxygen in the car and normal humiture in transportation by program, the user can be according to the livestock and poultry group size in the length of time, set a minimum ventilation curve, regulate the minimum ventilation in the car automatically.Under the situation that overload and superpressure occur, controller low pressure and high pressure input-output device use the quick-acting fuse that can reset, with holding circuit safety.Controller provided by the invention can also provide a kind of simulation test means by burn recording software, under this pattern, and outside temperature sensor signal conductively-closed, the user can be by the peripheral equipment of variation control of keyboard analog temperature.During the temperature curve operation, this function is invalid.The user can be provided with the temperature controlling upper limit and lower control limit, compares with the temperature set-point of setting when vehicle interior temperature, exceeds the deviation range of setting, and controller is reported to the police
During normal the operation, central processing unit carried out once record every 1 minute, and the design record capacity is the data in 10 years.Such as need to the data of meter record inquire about, can will extract on the SD card slave controller, by the PC software of special use the record data in the SD card are read then.By the various operations to PC software, the historical data that can inquire about arbitrary period.
Claims (2)
1. livestock and poultry transport vehicle environmental control with the SD card, comprise central processing unit, central processing unit connects communication interface, clock circuit and power circuit respectively, it is characterized in that, the input end of central processing unit connects temperature sensor, humidity sensor, keyboard input circuit respectively, the output terminal of central processing unit connects liquid crystal display circuit and SD card, the output terminal of central processing unit connects well heater by analogue quantity output circuit, and the output terminal of central processing unit connects the constant speed blower fan by the switching value output circuit.
